NZBGet 16.4-3 (R4x86)

Thanks to Andrea I was able to fix a bug in the NZBGet add-on for ReadyNAS OS 4 (x86) that could prevent NZBGet from starting up on some systems. The base problem was that this version was compiled against libssl1.0.2 but I forgot to include that lib in the add-on. Since some other add-ons already come with libssl1.0.2 it was already present on my testing box. Sorry for any inconvenience.
